Adding my support for this feature. I click location when I create a new entry, so I can see where exactly I wrote the journal entry. Having the ability to have this happen automatically when creating a new entry would be useful. It’s one less click for me, and sometimes I may forget to add the entry.
Something to consider is only adding the location automatically when the entry you’re creating is for the same day. If you are creating an entry from a few days prior (maybe you wrote it down by hand earlier), it shouldn’t automatically add your location.
